HAULlNG-CAN.

SPECIFICATION forming part ofLetters Patent No. 282,585, dated August '77, 1883.

Application filed February 12, 1883.

ToV all whom it mayconcerm:

Beit known that I, JOSEPH F. SWAB, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Hauling-Gans; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and gures of reference marked thereon,which form a part of this specification.

This invention relates to improvements in cans for hauling and transporting milk;` and it consists in the construction and arrangement ofthe several parts hereinafter described, and specifically pointed out in the claims.

In the drawings, Figure l is a plan of my can having the lidin place thereon. Fig. 2 is a vertical section of the can on line :12, Fig. l. Fig. 3 is a cross-section of the can on line y y, Fig. 2. Fig. 4 shows a vertical section of the inner metallic casing removed from the outer casing. Fig. 5 is a vertical section of the lid or cover, having the wooden disk and packing removed therefrom. Fig. 6 shows two views- 5o jointed by miter-joints a3, as shown.

a plan and a vertical section-of the iioat. Fig. 7 shows the can supported by its tilting stand. Fig. 8 shows in detail the improved tilting stand and ear to be employed in combination with my can, and Fig. 9 shows one of the angle strips or blocks in perspective and in cross-section.

This can is composed of a main outer casing of octagonal shape, an inner cylindrical removable metallic casing, and an interposed packing. I make the Outer casing of a convenient angular shape, preferably octagOnah-so that the ears or handles and the tilting devices may be readily attached thereto, and so that the operation of tilting for the purpose of emptying the can may be more easily and readily accomplished than could be accomplished with round cans.

a is the main outer casing, made of wood, and provided with the wooden bottom a. The casing is made of octagonal form, having the edges of its several sides or panels, a?, snugly In the inner angle formed by the contiguous edges (No model.)

of the sides or panels c?, I place the vertical angle pieces or strips c, which fit snugly into and fill the said angles, covering and bracing the joint and extending laterally therefrom a sufficient distance to give to the inner perimeter of the casing an almost circular form. These angle pieces or strips make the joints a perfectly air-tight,` give strengthy and durability to the casing, and give form to the inner perimeter to adapt it to receive the packingweb I). The casing is bound by the external hoops, c5 c, which are secured in place by any suitable means.

Transportation or hauling milk-cans are subject to very great exposure to rain and the heat of the sun, and are subjected to the roughest and hardest kind of handling, all of which puts them under the severest tests. In my can the outerv casing is made angular in form, having the joints covered on the inner side by snuglyfitting angle-blocks. The flat sides of the casing enable the hauler to get hold of and move the can with more ease, while the braced joints effectively resist the hard knocks to which the can is subjected. which possesses all the strength of a tubular can, and which may be handled with the most perfect ease. j

b is the packing interposed between the wooden casing a and the inner metallic casing, c. This packing is made, preferably, from/a web of felt or rubber, which is slightly elastic or which will yield under pressure. Frointhe web I first cut a circular piece or disk, b,which I lay on the bottom a. I next cut the web b, having a width equal to the depth of the casing and having a length equal to the vinner perimeter of the said casing. The ends of this web b are then placed together to give it a tubular form, and it is slipped down into and fits snugly against the inner face of the casing.

c is the inner cylindrical metallic casing. It slips down into the casing a and into the tubular packing-ring b. It is made slightly larger than the inner diameter of the tubular packing-ring, so that it will compress the latter outwardly and compactly against the inner face ofthe outer casing. The inner casing may be removed from the main casing and the tubular packing, as hereinafter explained.

c is an Overlapping depending rim connect- I have in this casing a forined to the top of the casing c, and extends outward over the upper end of the packing-ring Z) and over the upper end of the main casing, and is bent downward close to the outer side of the main casing, as Ashown in Figs. 2 and 4.

` This overlapping rim covers and protects the the casing c; but it mav be made in a separate detached piece, having its inner end turned down in a short lip, as indicated at c2 in Fig. 4. The lip cL will hold the upper end of the packing-ring out of the way and will permit the casing c to be lifted out. I employ this latter construction in cans which are not to` be subjected to severe handling. I prefer to make the rim c vfast to casing,ras hereinafter explained. It will be seen that the casing c may be lifted from its place in casing a, and when thus removed it may be set in water to cool the milk.

d is the lid, made j ust large enough to rest upon the top of and close the upper or open end of the inner casing, c. It is cylindrical in form, having a bottom plate, d, which rests upon and covers the casing c. It is also provided with a central tube, d2, open at both ends. A packing-disk, b3, islaid on the bottom pla-te, and over this is placed awooden disk, di. The disks d and b3 are made to fit snugly in the lid and around the central tube, d2. The upper edge of the lid is turned inward over the outer edge of the wooden disk, and the upper end of the tube dZ is turned outward and down onto the disk d3, as shown, thus making a very solid and compact cover.

d is a depending rim fixed to the under side of the cover d. It is set in slightly from the periphery of the lid, and is arranged to slip down into and snugly fit within the upper casing, c. The lid or cover thus provided serves to close the casingc when the latter is in place in or is removed from the outer casing, a. rIhe opening through the central tube, di, may be closed by small slide or pivoted valve d5.

c is the float employed in my can. Its upper plate is made like the iloat patented to me in Letters Patent No. 242,713. The u11- der portion of the float is left entirely open. The outer depending rim, c, touches the casing c, and the depending tubes c2 have their lower ends flush with or nearly ilush with the lower edge of the' rim c. When the milk is poured into the can, it rises within the iioat till it touches the lower portions of the depressed top. The top having the annular depression formed between its periphery and center, the milk will touch the lowest point of this depression, but will not rise to and touch the higher portions, because of the air which has been compressed below the top plate. XVhen the milk has risen, as indicated I prefer to make the rim c fast toin Fig. 2, there will be two spaces or chambersfilled' with compressed air-namely, one at the center and the other an annular space `at the periphery. These two bodies of compressed air operate together to cause the float `.to ride perfectly steady and hold the milk against all agitation. The float is not liable j to be broken or bent or otherwise injured, bel cause' the bodies of compressed air act as elastic cushions to preserve the float intact.

In Fig. 7 I show, in combination with my can, an ear, f, specially adapted to it, toeni able the person to better handle it when full or partially full of milk. rlhis ear f is made in the form shown in Fig. 8, having two short inwardly-projecting lugs, f, which are so arranged that they will catch on the arms g oi' j a tilting stand, g. The stand g is made just high enough so that its arms g will be under `the ear f when the latter, is raised. The ear is dropped onto the stand. and then the can may be tilted, as indicated in dotted lines, Fig.

7, for the purpose ofV emptying the milk.

For ordinary use in the spring and fall of the year this can may be constructed without the interposed packing. The inner casing, c, will be made large enough to iit snugly against the inner faces of the angle blocks or strips, made with concave surface a7, as yshown in cross-section, Fig. 9, and touch the middle points of the inner faces of the sides or panels a2. The inner casin g will be held perfectly se- ,cure I make the rim c in the manner hereinbefore described for all cans subjected to severe handling; but where the cans are to be handled -lightly the rim need not be turned down along the outer side of easing a, but may be extended only far enough to cover the upper ends of the packing-ring and of the panels c.

The tilting devices shown in Figs. 7 and S will be made the subject-matter for a further application for patent.

The can is provided with rollers secured to its bottom plate, as shown in Fig. 2, so that it may be readily moved about the Creamery.

Having thus described my invention, wh at l1 claim, and desire to secure by Letters Patent, 1s-
